I got 2 mag 5's in May....I have maybe 150 hours on them so far.
I got them cause my old man used cannons for over 20 years and has never had an issue with their "old" technology.
The 250 ft/minute retrieval rate is so darn fast compared to their old technology.
They have a feature where they stop at the water line automatically. They stop so fast that they bounce a good 6-8 inches, which puts alot of strain on the cable. I went over a wave just as the rigger stopped, so the ball was out of the water when it bounced....and the cable snapped. Lost a 10 pound ball last week when that happened. Watched my fish finder and saw the ball drop all they way to 147 feet down, as I stared at my wallet (terminator kit: $25, new cable isolators which don't come in the terminator kit which require a special order for the auto stop to work: $20 from bay distributors, new line release: $10, and a new 10lb shark ball at $60)
The pulley system on the end sucks compared to their old models...if there is slack in the line when you bring in the cable, the cable has a tendancy to come off the pulley, requiring you to remove 5 screws to disassemble the pulley head to get the cable back in the track. I keep a philips screwdriver in the boat just for this reason.
Other than that they are excellent riggers.
I would not get the telescopic arm unless you need the spread.
I would have bought scotties if I had the time over.
Want to buy mine so I can go get the scotties (I am in Ottawa also)?
